I use the Harman pb105 pellet boiler to heat my home, which is newer and well insulated. I've always wondered what is the best temp to decrease my thermostat to during the day to conserve pellets. Any ideas?? Seems like if it is too low, then the boiler burns a lot of pellets when there is the big call for heat when i get home. The house temp when i get home is 68. Would love to get other people's thoughts on this....thanks for any help....
